maybe someone in the cosmos of this not so user friendly forum can help me with this.

I am in the very early stages of developing a clip launching interface and eventually full on video manipulation application for use with the monome or launchpad and DIY midi controllers. I have come up with a rough draft of the clip launching part of the patch however it seems to be causing my end frame rate to drop down to about 15-30 fps. this is especially bad since i have not even gotten into processing the video at all yet. anyway, the patch below is the main clip launching part, there needs to be 64 of them. If anyone could take a look or give any advice it would be appreciated! also i can post the rest of the patch if anyone is interested.

Could you copy compressed in Edit before sending your patch...

Hello,

Could you copy compressed in Edit before sending your patch...
Give us your setup etc...
and let's see if someone can help you

I attempted to load this code in order to re-paste it copy compressed but it is not complete.

Please add it again and I'll delete the first attempt.

its not letting me post the compressed code at all, or any code anymore! tried posting the compressed code in the backticks like it said to at the bottom also and all i got was that blank reply that you can see three posts up. for some reason whenever i try to post the code it spits me back out to the front page of the forums now. tried with both firefox and safari. got some serious bugs in the forums here!

UPDATE: seems as though the problem fixed itself. tried several times throughout a half an hour period and eventually it worked?

EDIT: each of the 64 windows will need to be edited slightly for the button that they are supposed to represent on the launchpad. the large sel at the top of the sub patcher window will need to have its first number changed to the corresponding midi note for the pad that it will represent and the same number will need to replace the one in the message box attached to the s padnote object at the bottom of the sub patcher. for example the pad in column 1 row 1 will need the message 0 which is the current messages in the boxes. column 2 row 1 will need the number 1. and column 1 row 2 will need the message 16, and so on and so forth. please let me know if this does not make sense. im not always the best at describing things.

ok, so there needs to be 64 of these

this part is for midi the midi communication between the launchpad and the clip window

and this portion is for playback of the video

the way that everything works is you drag and drop a video file into one of the 64 clip windows, which will send a bang to the jit.qt.movie to display the first frame in the matrix over the dropfile, acting like a thumbnail. this also sends midi note info to the launchpad telling it to light up the corresponding led with light green. when you tap the corresponding button you can select the clip with the first tap which will lite the pad up with full green and then a second tap will light the pad red and send the clip info to the movie player patch for playback and further manipulation. so far there are two channels which you can have clips playing on and only one clip can play on a channel at a time. when you select a clip with the launch pad the user 1 and user 2 buttons will tell you what channel is currently selected for that clip. all leds update as changes are made, eg, only one red led per playing channel of video.

for development purposes there are two hot keys that i made for when the launchpad acts funny. alt-p is panic and will reset the lunchpad. alt-r will resend the current midi data to the launchpad. if you need to reset the midi data you may need to press one of the user buttons at the top of the launchpad before it will start to send and receive messages again. dont know why it does that yet but im working on it.

64 is a lot of pwindows to have viewable at once. make sure you've set the dimension of each one to as small as possible for your specific needs (it is currently the default of 320x240).

you would be better off with a single pwindow, and displaying your clips by compositing into a single matrix using src/dst dim attributes, or better yet, with opengl.

it is hard to tell from your poly~ movie patch, but make sure that the qt.movies are not all playing at once when they are read in (@autostart 0 would do the trick), and make sure they are being banged and started only when active.

other than that, you probably want to get rid of unnecessary interface objects that are updated at framerate (eg. the jit.fpsgui in the poly~ patch) in clean up your patch in general so you can more easily diagnose the problem.

and of course the vade optimizations will help:

thank you, I am not too familiar with the gl aspect of jitter yet these vade examples should really help out!

I'll post an update as soon.


alright so i pretty much redid most of the clip launching window, seems as though this has helped the frame rate dramatically however i have run into a new problem. now I cant get the tumbnails to post into their positions in the consolidated pwindow. everything worked fine when i was putting it together and then all the sudden it stopped working and i cant seem to figure out why. im sure that i must just be doing something stupid but if someone could take a look I would appreciate it.

here is the new clip launching window, (It may take a sec for it to open into patching mode, its rather large)

EDIT: It seems that this patcher has grown far too large to post to the forums (compressed the code is still 151 pages) if anyone would be interested in helping me to figure this out please shoot me an email an i can send the patch over in your direction. wrober1@saic.edu

nevermind, problem fixed, although for some reason named matrixes arent working for me right now so i have to connect everything via patch cords. hmmm.

Ok, the clip launching portion of the app is done (for now) . would probably be useful to anyone who would like to use a novation lauchpad to trigger clips in a video patch. If anyone is interested I can send the full patch. currently it allows for 64 clips to be loaded into a window which displays a thumbnail of the clip in a grid. there are two channels for video, and only one clip can be played on a channel at a time. led pads update and refresh accordingly. could also be modified for any type of grid controller (I am eventually going to add support for the monome/arduinome and ohm 64 but thats prolly going to be a little while). if you think that this may be useful to you email me! wrober1@saic.edu

Sources of much frustration and low frame rate are these jitter is
